The three applications are different anomalies, as an example, SCP-XXXX-A is an application that reproduces music, includes only one song, that causes seizure and mental issues, SCP-XXXX-D, an application that invokes a humanoid entity, of which drags its victims after some hours, the same tortures the subject mentally. I'd like to see suggestions and feedbacks, constructive feedbacks are appreciated!Note: I thought I needed to insert the draft link when someone asked for it, now it's here:http://scp-sandbox-3.wikidot.com/stin-phone

In the Drafts and Critiques forum, a sandbox link is always needed. In Ideas and Brainstorming, meant to address concepts before the draft stage, a sandbox link should only be provided if/when requested. There are two sets of guidelines for the two forums. ~Zyn

Okay, giving this a quick read since it fell to page 4 with no replies. Here are my thoughts:

Right from the start, the containment is problematic.

SCP must be contained in an aluminum box that is currently located at the Site-██, under the sea.

This SCP may not be in contact with internet or any kind of signal.

Why an aluminum box? What's so special about aluminum that it is required? Also, "under the sea" is a little vague (and also a Disney princess movie song) and you never specify if it needs to have any sort of secondary holding besides the box. If it's just in a regular box, does that mean anyone can access it? Also, refer to the SCP object using its designation. Just "SCP" doesn't work. Furthermore, don't refer to an SCP object as "the SCP", since in-universe that refers to the containment procedures. The actual thing in containment is the "SCP object". Also, "internet" and "signal" are not physical things, so a physical object can't really come in contact with those things anyway. If you mean that it should not be allowed to receive any such signals, then why not put it in a Faraday cage or something else capable of blocking those things?

With regards to the rest of the article, it's pretty bland. It's a bunch of seemingly-unrelated concepts all combined together into one piece without much reason, and none of those concepts are particularly interesting in themselves. The "SCP-XXXX-A is an application that reproduces music, the application only includes one song, called "Ear Death", upon hearing the song, subjects experience extreme pain on the ears, that increases at each second passed, after one minute, subjects experience a seizure leading to death." part comes off as kind of creepypasta-y and follows the same sort of "otherwise-mundane thing that kills people" formula that tends to result in over half the deletions that happen every day on the site.

I recommend getting the base idea polished up in the Ideas and Brainstorming forum before you try fixing the draft. Go to that forum, post a quick summary of the concept you want to write up (don't link the draft unless someone asks), and reviewers there can help you make the idea less jumbled and more solid.
